FLOATING-THREAD CUTTER.

Application filed December 27, 1915.

To all whom it may concern:

Be it known that we, GEORGE E. DRUM, a citizen of the United States, and JAMES H. SKITI, a subject of the King of England, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Floating-Thread Cutters, of which the following is a specification.

The object of the invention is to improve the construction of floating thread cutters such as are employed in connection with the manufacture of stockings with double soles.

The invention is more fully described in the following specification and clearly illustrated in the accompanying drawing, in which:

Figure 1 is a view in side elevation of the invention, Fig. 2 is a view partly in side elevation and partly in longitudinal vertical section showing one section of the stocking tube raised, Fig. 3 is a top plan view of a fragment of the lower section of the stocking tube, and Fig. 4 is a transverse vertical sectional View taken through line 4-4 of Fig. 1.

In the drawing, reference character 1 designates the base, upwardly from which extends a bracket plate 2 which, with the casing 2, houses the operating mechanism. Extending horizontally from the bracket plate 2 is the stocking tube composed of two sections 3 and 4, the latter being the lower one and aflixed to the bracket plate 2 and the former being hinged to said bracket plate by transverse horizontal pin 5 passing through ears 6 on opposite sides of the tube section 3 and plate 7 which is between said ears and on the bracket plate 2. The operating lever 8 which enters the stocking tube from the casing 2 is pivoted on rock shaft 9, the ends of the latter being received in blocks 10 cast integral with the lower section 4 of the stocking tube. Stud bolts 11 extend upwardly from said blocks 10 and receive a removable bridge plate 12 which is held down in place by nuts 14 applied to said bolts 11. This bridge plate 12 substantially centrally between its ends is provided with a rearward extension having its upper and lower rear corners rounded to provide a double acting latch strike 15. A bracket 16 is secured to the inner face of the upper wall of the upper section 3 of the stocking tube and to the downwardly ex- Specification of Letters Patent.

Serial No. 68,949.

tending extension 17 thereof is pivoted a latch 18 by pintle 19. This latch is foot shaped, the toe 20 thereof being rounded to engage with the strike 15 and the heel 21, which extends rearwardly, having attached thereto and to the upper-wall of the tube section 3 a coil spring 22. By grasping the outer ends of the two tube sections 3 and 4, the operator may forcibly draw the two sections 3 and 4 apart, the latch moving rearwardly over the rounded lower portion of the strike and compressing the spring 22. In closing the stocking tube, the upper section 3 is forced down upon the section 4, the toe of the latch riding over the upper rounded edge of the strike 15 against the tension of the spring 22 and then being forced by said spring to the dotted lineposition shown in Fig. 2. Forward movement of the latch under the action of the spring 22 is limited by a finger 24 shown in dotted lines in Fig. 2, which finger engages the upper wall of the tube section 3 when the latch toe has reached its proper forward position.

The lip 3 of the tube section 3 is provided with an inset hook 25 which extends rearwardly above the upper wall of said tube section 3 and forms. a means whereby, upon removal of a stocking from the tube, said stocking is turned inside out.

The forward extension of the operating lever 8 is equipped with knives 27 which coact with shear plates 28 set into the side walls of the tube section 4. When the tube sections 3 and 4 are mated as shown in Fig. 1, slots 30 are provided therebetween to receive the float threads so that they will pass between the cutting elements 27 and 28. The float threads are drawn tight by tension rods 31 which include each a horizontal portion substantially parallel with the slots 30 and an inclined upwardly extending free end portion. The horizontal portions of these tension rods have their rear ends secured to a substantially horizontal transverse arm 33 which is provided centrally between its ends with a downwardly extending stem 34 which is vertically adjustable within a vertical'hole bored downwardly in a mount block 36, said block 36 being cast with the bottom wall of the'lower tube section 4. A set screw 37 passes from the front into the mount block rods and knives, of adjusting the tension device and knives, and of repair and care.

What is claimed: 1. In a device of the type described, a frame, a tubular member composed of upper and lower sections providing thread slots between their meeting faces, the lower section secured to the frame, the upper section being hinged to the frame and separable from the lower section, and a cutter and tension means within the tubular member and mounted solely upon the lower section.

2. In a device of the type described, a frame, atubular member composed of upper and lower sections providing thread slots between their meeting faces, the lower section secured to the frame, the upper section being hinged to the frame and separable from the lower section, cutter and tension mechanism within the tubular member, a

strike plate extending across the upper edges of the lower section, and a spring pressed latch carried by the upper section and adapted to ride over the strike plate in either direction when the upper section is separated from the lower section.

8. In a device of the type described, a frame, a tubular member composed of upper and lower sections providing thread slots between their meeting faces, the lower section secured to the frame, the, upper section being hinged to the frame and separable from the lower section, cutter and tension mechanism within the tubular member, a strike plate extending across the upper edges of the lower section and having rounded upper and lower edges, and a double acting latch adapted to engage and disengage said rounded edges of the strike plate when the said hinged section is closed and opened respectively.

In testimony whereof we aflix our signatures in presence of two Witnesses.
